3D Transform Onscreen Controls Display
It is possible to display a subset of the 3D transform onscreen controls.
• Press the Comma key (,) to display the axis arrows (but not the rotation handles or
scale handles).
• Press the Period key (.) to display the rotation handles (but not the axis arrows or scale
handles).
• Press the Slash key (/) to display the scale handles (but not the axis arrows or rotation
handles).
When you press any of the above keys a second time, the display switches back to
the default, with all three of the onscreen controls visible.
3D Transform HUD Controls
In addition to the onscreen controls, the HUD provides another method of transforming
objects in 3D space.
Choose an axis type.
Drag to move Z.
Drag to move X and Y.
Drag to move X and Z.
Move: Three controls in the Move section of the HUD let you drag the selected object
in one or more axes at once. Drag inside one of the Move controls to change the relevant
parameter values of the object in the Canvas.
• Move Z: Drag here to move the selected object in the Canvas along the Z axis. Dragging
to the right increases the Z value, and dragging to the left decreases the Z value. Hold
down the Command key when dragging to simultaneously scale the object as it is
translated (moved), preserving its size relative to the camera.
• Move XY: Drag here to move the selected object in the Canvas along the X and Y axes.
Dragging right or left increases or decreases the X value. Dragging up or down increases
or decreases the Y value. Using this control is identical to moving a 2D object directly
in the Canvas. Hold down the Command key when dragging to constrain movement
to the axis corresponding to the initial direction of the drag.
